That is strange, since the first thing I tried is this: Assuming[Element[x, Reals], NSolve[x - Sinh[x] - 1 == 0, x]] and it did not work ! I see from help now that NSolve takes Reals as second argument. But this is not very consistent with how other functions work, by using Assuming.

@Nasser I don't think the assumption is taking effect on the NSolve "Block[]"
